invention relates to apparatus for projecta tape such as a stock provedapparatus for projecting two images from erably me tape upon differentscreens and preffrom a single light source.

The principal feature of the invention, as

briefly described, consists in two with a condensing lens for each,mirapertures,

opposite light rors and usually also other condensing lenses forproperly directing and dividing a light beam from a single source topass through the respective apertures and the condensers locatedadjacent the apertures, means for the ticker in a generally the supportor enclosure and their condensers and jective lenses,

guiding the tape from circuitous course about for the light aperturesover the apertures, ob-

and mirrors properly arranged to direct the light beams from therespective apertures to screens located in Desirably, in some casestwisted laterally through a ticker and the projector so desiredpositions.

the tape is reversed, or half -turn between the that it passes over thelight apertures with the printed face inward thus reducing to a minimumthe number of mirrors which are necessary to the respective screenscharacters in run directly t to direct the light beams and present thetape proper positions thereon, although if desired the tape may 0 theprojector and pass over the apertures with printed side outward, with adifferent mirror hereafter.

arrangement, as fully explained In a preferred arrangement the lightapertures are in vertically opposite positions and the tape passes aboutthe projector in a course which is in a vertical plane. These and otherfeatures, capabilities and advantages of the invention subjoine'd detailwill appear from the description of one embodiment thereof, illustratedin the accompanying drawings, in which Fig. 1 is a bodying the inventionin one form,

the drawings is largely dia- I and downward. to 3 the projector 1includes the lamp housing 2, here shown in simple form, which may reston a support such as a floor 3, Fig. 1, or other support in a convenientposition with relation to the definitely located screens. If the supportsuch as 3, is in the nature ofa 5 floor it has an aperture 4 for one ofthe light beams. I

The lamp housing has another compartment or extension 5 forming ahousing for certain lenses and also arranged for movement of the m tapeabout it, or about three of its sides. At opposite sides or the lenshousing 5 and preferably in upper and lower sides are light apertures 8and 1 respectively of a length corresponding to a desired length oftape. A con- 15 densing lens 8 is supported within the upper wall of thehousing in centered relation to the upper aperture and anothercondensing lens 9 is secured within the lower wall in centered re- 1lation to-the lower aperture.

S uitablc condensing lenses H are arranged with their common axis at aright angle to the common axis of/the condensers 8 and 9, the condenserll being located at a light aperture I3 in the lamp housing. Thearrangement may be such as shown, to eliminate all but a desired part orthe total light beam from the lamp through the first condensers Ill andH. A reflector M is located behind the lamp.

Mirrors l5 are supported on the front or vertical wall of the condenserhousing 5, these being arranged at a right angle to each other, and atan angle of 45 to the respective beam axes. Each mirror interceptsone-half the light beam from condenser II and directs this light to thecorresponding condensers 8 or 9.

Suitable objective lenses are mounted inv a casing l6 above the upperlight aperture 8 and another objective I1 is supported below the loweraperture 1. The beam through objective I6 is directed by a single mirrorl 9-at a angle to a screen 20 and the beam through objective i1 is firstdirected horizontally by a mirror 2| arranged at a 45 angle, to anothermirror 22 erand from. mirror 22 is 45 thrown upward to another 45" anglemirror 23 which directs the light beam to the second screen 24. Thescreen positions may, of course, be different with relation to theprojector, the screen and mirror arrangements illustrated being a sufli-5o cient example ofsuchjarrangements suitable .to a multiple projectorin which the two beams are preferably initially thrown oppositely upwardThetapetfl issuing from the tapeprinter or at the top of the lens andmirror housing 5, at

illustrated in detail.

the side adjacent the ticker, and from. guide 33 is directedover the topof the housing and over the upper light aperture 6 to, a guide, whichmay be a roll 34, at the side of the housing away from the ticker; thetape then passes down at the right of the housing 5, as viewed in Fig.l, to another guide roil 34a, is then directed across and below thelower light aperture I to a guide roll 85 and thence to the feed rolls.36 of the tape puller l1 driven by a motor 38 and also arranged tooperate a rewind reel 39 in the usual way. In one preferred arrangement,as above referred to, the tape is so supported or guided that it hasbetween the ticker and the projector a transverse one-half tum or twistas at 40. As the tape issues from the ticker the printed surface isupward and the half-turn or twist brings the printed surface downward orinward in relation to the light aperture and the tape passes about theprojector housing and over the apertures in this position. In such acase the guides, such as 33, ,llaand may be provided with raised,straight or annular ribs 1' (Fig. 5) to engage unprinted longitudinalstrips of the tape surface between or at the sides of the lines ofprinting thereon, thus avoiding any contactof the printed surface withguide surfaces and consequent blurring of the print; Such guides aredisclosed in my copending applications, and are not here To facilitatethe shortest and most direct travel of the tape from the ticker to thepro- Jector, with the half-twister turn in the tape as above referredto, the ticker is preferably placed at adiagonal or oblique angle to theproiector,asshown inFigs. 1 and 3.

The tape puller or its motor is controlled by a suitable'switch in aswitch box 4| supported on the projector, as best shown-in Fig. 3, andinserted in the puller driving or controlling -cir'- out 41. Fig. l, andthe switch is controlled by a follower, such as a finger 44 running on atape loop II between the ticker and the projector, this -loop portion ofthe tape being specifically as shown, between the transverse twist l0and the first projector guide 33. The-follower and switch controltheaction of the tape puller in accordance with ticker operation, in amanner 7 well understood in the art. While, as shown, the

switch directly controls the power circuit 42 of the motor,'it mayotherwise be inserted in another controlling circuit. as for example,when,- the motor continuously and the puller is controlled by a brake orclutch and in such case the controlling switch may be placed in the.

brake or clutch circuit. Desirably, atape retarder such as the frictionmember 5. acts on the tape at a point before it reaches the first(upper) light aperture 6, this device acting ina known manner toappiymoderate'frictional retarding force'to the tape to steady itsmovement about the-projector housing and over the .two light apertures,and reduce jerking on the tape anterior to the projector and for otherreasons as understood by skilled persons.

By the described tape and mirror arrange-'- ment, the image of the tapestrip located at each light. aperture is thrown uponthe respectivescreen 20 or 24 in proper position. Thus, with respect to screen2.,which is viewed from the left of Fig. 2, the inverted tape image atthe light aperture 6 is reversed by the objective and thrown upon thescreen in proper position, and the stretch of tape at the lower aperture1 presents thecharacters in the same inverted position in relation toits light beam. This image is reversed three times by the objective "andmirrors 2| and 22 and is therefore thrown upon the screen 24 by mirror23, in proper position for observation from the right of the screen.

The described structure or arrangement including oppositely locatedupper and lower light apertures, and the means for guiding the tape overthe first aperture, down alongside the projector housing and then overthe second aperture, without any transverse twist or bend in the tapefrom the point where it approaches the first aperture to the point whereit leaves the second aperture, avoids difficulties or disadvantages ofprevious duplex projecting arrangements, such for example as anarrangement in which the light apertures are adjacent and parallel andthe tape must be transversely twisted and reversed in a directionbetween the two apertures, with attendant dimculties, such as stickingor binding of-the tape on the reversing guide. with the present.arrangement, also, the tape is directed in thecontinuous course in onevertical plane and the pull exerted on it by the tape puller istherefore effective to properly advance the tape a without undue strain..ierkingor breaking of the tape, etc. j 3 In some-casesthe tape may beadvanced directlyfrom the ticker to the projector without ror i0, andthrown to mirror ll which reflects the image in proper position on thescreen, be

cause of the two reversals of the printed characters' provided by theobjector'and mirror ll,

and similarly for screen 24 there are similarly arranged mirrors 6! and63 which, in conjunction with the mirrors 2| and 22 as previouslyreferred'to. throw the beam from the lower light apertm'e in properposition on screen II.

The described arrangement of opposite condensers, such as C and 1, eachcorresponding to.

one of the objectives permits the condenser to be chosen with regard tothe focal length of the particular objective so that for example eitherobjective may have any desired length and be positioned at acorresponding distance from its condenser and light aperture, asindicated in Fig. 2, where the upper objective l6 has a relatively shortfocal length and the lower objective has a greater focal length,corresponding to a greater total distance from'the corresponding lightapertureof the screen 24, and the-condensers I and O are of differentforms corresponding to the stated focal lengths of the objective. 1

The guide, such as 32, Figs. 1 and 3, e under and at the edges of thetape as it comes from. the ticker and before formation of the transversetwist II and is employed whenever necessary to prevent improper lateralmovement of the tape at or adjacent the point where it leaves the tickerand is formed into the transverse twist or half-turn 40. r

It is obvious that various changes and'modiflcations may bemade in thedetails of construetion without departing from the general spirit of theinvention set forth in the appended claims.
